  Abstract

The overall goal of this study was to analyze life safety measures at a large domestic financial company's data center through fire and evacuation simulations that account for evacuation risk factors. Evacuation safety was evaluated using typical methods in performance-based design. Available Safe Egress Time (ASET) and Required Safe Egress Time (RSET) were comprehensively assessed to determine the efficiency and safety of evacuation routes. The results of these assessments were used to derive practical improvement measures. ASET simulations based on carbon monoxide (CO), carbon dioxide (CO2), and oxygen (O2) concentrations indicated the maximum allowable evacuation time for Exit 1, all exceeded 600 seconds. ASET based on temperature and visibility were calculated at 180 seconds and 145.5 seconds, respectively. The RSET for Exit 1 was calculated to be 113.7 seconds. As the RSET is less than all simulated ASETs, it confirmed that safe evacuation was possible for Exit 1. ASET simulations for Exit 2 determined evacuation times based on CO, CO2, and O2 concentrations were 565.4 seconds, 544.5 seconds, and over 600 seconds, respectively. ASET based on temperature and visibility were 165.4 seconds and 135 seconds, respectively. The RSET for Exit 2 was determined to be 125.6 sec, less than all simulated ASETs, and indicated evacuation safety was ensured. In conclusion, the RSETs for Exit 1 and 2 were less than all simulated ASETs. This results of this study confirmed there was enough time to evacuate safely at both locations.
